Cannabis Exposure During Pregnancy And Neural Mechanisms Of Parenting: Assessing Neural Responses To Infant Cues And Parenting Outcomes, Shannon Powers
Cannabis Exposure During Pregnancy And Neural Mechanisms Of Parenting: Assessing Neural Responses To Infant Cues And Parenting Outcomes, Shannon Powers
Electronic Theses and Dissertations
As legalization of cannabis and cannabinoids spreads in the United States, access and use of cannabis during the prenatal period has increased. There is limited knowledge on the effects of prenatal cannabis use on the parental brain. One way to identify potential effects of cannabis on parenting is through studying parenting brain functions and behavior. Cannabis use disorder (CUD) has been shown to be associated with lower positive parenting and lower sensitivity to infants, but it is unclear by what mechanisms. The following two studies address this gap in knowledge by examining the association between cannabis use during the prenatal …
Dancing The Storm: Neurobiological Correlates Of Trauma-Related Psychopathology In Youth Resettled As Refugees, And The Efficacy Of Creative Arts And Movement Therapies To Address Trauma-Related Psychopathology, Lana Ruvolo Grasser
Wayne State University Dissertations
Exposure to stress and trauma activates key adaptive pathways, including the sympathetic adrenomedullary system and the immune system, which can result in long-term health impacts of trauma especially when experienced during sensitive developmental periods. Alterations in these systems are measurable through non-invasive methods including skin conductance response (SCR), fear potentiated startle (FPS), and inflammation. Research regarding the impact of trauma, and more specifically posttraumatic stress disorder, has primarily focused on adults, and there is a paucity of neurobiological research in displaced populations—like refugees—who may experience higher rates of trauma exposure and related psychopathology. The present study measured SCR to a …
The Role Of Socioeconomic Status In Cognition And Brain Health Across The Lifespan, Erica Chung
The Role Of Socioeconomic Status In Cognition And Brain Health Across The Lifespan, Erica Chung
Honors Theses
Disparities in cognition are inevitable throughout the lifespan due to socioeconomic gaps. Individuals of lower socioeconomic status (SES) may have fewer access to environmental resources, especially with regard to education, than individuals of higher socioeconomic status. Differences in available resources from a young age may affect brain development, leading to detriments in cognition and behavior, further impacting socioeconomic success in adulthood. In the present study, we modeled the development of the dorsolateral prefrontal cortex (DLPFC) and changes in cognitive function throughout the life trajectory in the Nathan Kline Institute for Psychiatric Research Rockland Sample. The DLPFC volume was predicted to …
Multiple Approaches To Auditory Rhythm: Development Of Sustained Musical Beat And The Relation To Language, Development Of Rhythmic Categories Via Iterated Production, And A Meta-Analytic Study Of Neural Entrainment To Beat, Karli Marie Nave
UNLV Theses, Dissertations, Professional Papers, and Capstones
Rhythm is ubiquitous to human communication, coordination, and experience of music. In this dissertation, I address three empirical questions through three different methodologies, all of which contribute to the growing body of literature on human auditory rhythm processing. In Chapter 2, I present a registered report detailing the results of independent conceptual replications of Nozaradan, Peretz, Missal, & Mouraux (2011), all using the same vetted protocol. Listeners performed the same tasks as in Nozaradan et al. (2011), with the addition of behavioral measures of perception. In neuroscience, neural correlates to musical beat perception have been identified, yet little to no …
The Cerebellum's Relationship To Language Function Following Perinatal Stroke, Carolina Alexis Vias
The Cerebellum's Relationship To Language Function Following Perinatal Stroke, Carolina Alexis Vias
FIU Electronic Theses and Dissertations
While recent studies have demonstrated the association between the cerebellum and higher-order cognitive functioning, it is still unclear how volumetric differences of specific regions of interests within the cerebellum across typical and atypical development are related to language function. We have done so by measuring the volume of cerebellar subregions of healthy controls, and compared the volume to behavioral measures of language function. We then followed with an analysis of the cerebellum’s relationship to language function following perinatal stroke, which provides us with a greater knowledge of the impact of a cortical injury on cerebellar development and the cognitive outcomes …
Aberrant Maturation Of The Uncinate Fasciculus Follows Exposure To Unpredictable Patterns Of Maternal Signals, Steven J. Granger, Laura M. Glynn, Curt A. Sandman, Steven L. Small, Andre Obenaus, David B. Keator, Tallie Z. Baram, Hal S. Stern, Michael A. Yassa, Elyssia Poggi Davis
Aberrant Maturation Of The Uncinate Fasciculus Follows Exposure To Unpredictable Patterns Of Maternal Signals, Steven J. Granger, Laura M. Glynn, Curt A. Sandman, Steven L. Small, Andre Obenaus, David B. Keator, Tallie Z. Baram, Hal S. Stern, Michael A. Yassa, Elyssia Poggi Davis
Psychology Faculty Articles and Research
Across species, unpredictable patterns of maternal behavior are emerging as novel predictors of aberrant cognitive and emotional outcomes later in life. In animal models, exposure to unpredictable patterns of maternal behavior alters brain circuit maturation and cognitive and emotional outcomes. However, whether exposure to such signals in humans alters the development of brain pathways is unknown. In mother–child dyads, we tested the hypothesis that exposure to more unpredictable maternal signals in infancy is associated with aberrant maturation of corticolimbic pathways. We focused on the uncinate fasciculus, the primary fiber bundle connecting the amygdala to the orbitofrontal cortex and a key …
Maternal Hpa Axis Function During Parenting Is Associated With Reduced Brain Activation To Infant Cry And More Intrusive Parenting Behavior, Andrew Erhart
Electronic Theses and Dissertations
Previous research indicated that maternal cortisol function and maternal brain response to infant stimuli are separately related to differences in parenting behavior. Evidence from animal models have demonstrated that chronically high cortisol concentration alters brain structure and function, suggesting that studying these two mechanisms together may further improve understanding of parental behavior in human mothers. First time mothers of infants aged 1-7 months old (M age = 3 months) were recruited to participate. Mother’s cortisol concentration was measured during a naturalistic interaction with their infant and their behavior was coded for maternal sensitivity and nonintrusiveness. In a separate session using …
Characterizing The Development Of Episodic Memory And Assessing The Reliability Of Fmri Measures, Lingfei Tang
Characterizing The Development Of Episodic Memory And Assessing The Reliability Of Fmri Measures, Lingfei Tang
Wayne State University Dissertations
The ability to remember past events is critical for everyday life and showed robust improvement over development from childhood to adulthood. With advances in noninvasive neuroimaging methods such as functional MRI in recent years, research efforts have been focused on identifying neural correlates underpinning developmental gains in memory performance. In my dissertation work, using a widely-validated subsequent memory paradigm, I aim to characterize functional MRI correlates of memory development. Specifically, I focused my investigation on identifying age differences in the functional patterns of two brain regions critical for memory, the prefrontal cortex and the hippocampus. Focusing on the prefrontal cortex …
Resting-State Functional Connectivity In Youth With Gender Dysphoria, Felix L. Garcia
Resting-State Functional Connectivity In Youth With Gender Dysphoria, Felix L. Garcia
Dissertations, Theses, and Capstone Projects
Current developmental models of gender identity and gender dysphoria (GD) lack sex-specific profiles of brain function that differentiate between typically-developing and cross-gender identified youth, as postulated by models like the unified theory of the origins of sex differences (Arnold, 2009) and the neurobiological theory of the origins of transsexuality (Swaab & Garcia-Falgueras, 2009). Previously, investigators have used brain imaging modalities such as Resting-State functional Magnetic Resonance Imaging (R-fMRI) to demonstrate differences in resting-state functional connectivity (RSFC) between typically-developing male and female youth, and between typically-developing and GID-diagnosed youth. In the present pilot study, I used R-fMRI to investigate differences in …
A Single-Subject Evaluation Of Facilitated Communication In The Completion Of School-Assigned Homework, Nancy A. Meissner
A Single-Subject Evaluation Of Facilitated Communication In The Completion Of School-Assigned Homework, Nancy A. Meissner
Antioch University Dissertations & Theses
Few projects have combined quantitative and qualitative approaches in the analysis of facilitated communication as did this study of a 17-year-old nonverbal autistic male responding to homework questions using facilitated communication. Findings were consistent with prior studies: Tim was minimally able to produce correct responses independent of facilitator influence under controlled conditions; whereas, at least some typed messages in the spontaneous narratives appear to be his authentic communications independent of facilitator control.
An overview of the history of facilitated communication, its related research, and the heated debates around its validity are presented. Disparate findings between controlled and non-controlled circumstances are …
Family Income, Cumulative Risk Exposure, And White Matter Structure In Middle Childhood, Alexander J. Dufford, Pilyoung Kim
Family Income, Cumulative Risk Exposure, And White Matter Structure In Middle Childhood, Alexander J. Dufford, Pilyoung Kim
Psychology: Faculty Scholarship
Family income is associated with gray matter morphometry in children, but little is known about the relationship between family income and white matter structure. In this paper, using Tract-Based Spatial Statistics, a whole brain, voxel-wise approach, we examined the relationship between family income (assessed by income-to-needs ratio) and white matter organization in middle childhood (N = 27, M = 8.66 years). Results from a non-parametric, voxel-wise, multiple regression (threshold-free cluster enhancement, p < 0.05 FWE corrected) indicated that lower family income was associated with lower white matter organization [assessed by fractional anisotropy (FA)] for several clusters in white matter tracts involved in cognitive and emotional functions including fronto-limbic circuitry (uncinate fasciculus and cingulum bundle), association fibers (inferior longitudinal fasciculus, superior longitudinal fasciculus), and corticospinal tracts. Further, we examined the possibility that cumulative risk (CR) exposure might function as one of the potential pathways by which family income influences neural outcomes. Using multiple regressions, we found lower FA in portions of these tracts, including those found in the left cingulum bundle and left superior longitudinal fasciculus, was significantly related to greater exposure to CR (β = -0.47, p < 0.05 and β = -0.45, p < 0.05).
General And Emotion-Specific Alterations To Cognitive Control In Women With A History Of Childhood Abuse, Kristen L. Mackiewicz Seghete, Roselinde H. Kaiser, Anne P. Deprince, Marie T. Banich
General And Emotion-Specific Alterations To Cognitive Control In Women With A History Of Childhood Abuse, Kristen L. Mackiewicz Seghete, Roselinde H. Kaiser, Anne P. Deprince, Marie T. Banich
Psychology: Faculty Scholarship
Background
Although limited, the literature suggests alterations in activation of cognitive control regions in adults and adolescents with a history of childhood abuse. The current study examined whether such alterations are increased in the face of emotionally-distracting as compared to emotionally neutral information, and whether such alterations occur in brain regions that exert cognitive control in a more top-down sustained manner or a more bottom-up transient manner.
Methods
Participants were young adult women (ages 23–30): one group with a history of childhood physical or sexual abuse (N = 15) and one with no trauma exposure (N = 17), as assessed …
Abnormal Dendritic Maturation Of Developing Cortical Neurons Exposed To Corticotropin Releasing Hormone (Crh): Insights Into Effects Of Prenatal Adversity?, Megan M. Curran, Curt A. Sandman, Elysia Poggi Davis, Laura M. Glynn, Tallie Z. Baram
Abnormal Dendritic Maturation Of Developing Cortical Neurons Exposed To Corticotropin Releasing Hormone (Crh): Insights Into Effects Of Prenatal Adversity?, Megan M. Curran, Curt A. Sandman, Elysia Poggi Davis, Laura M. Glynn, Tallie Z. Baram
Psychology: Faculty Scholarship
Corticotropin releasing hormone (CRH) produced by the hypothalamus initiates the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the body’s stress response. CRH levels typically are undetectable in human plasma, but during pregnancy the primate placenta synthesizes and releases large amounts of CRH into both maternal and fetal circulations. Notably, placental CRH synthesis increases in response to maternal stress signals. There is evidence that human fetal exposure to high concentrations of placental CRH is associated with behavioral consequences during infancy and into childhood, however the direct effects on of the peptide on the human brain are unknown. In this study, we used a …
Relationships Between Age And White Matter Integrity In Children With Phenylketonuria, Erika M. Wesonga
Relationships Between Age And White Matter Integrity In Children With Phenylketonuria, Erika M. Wesonga
Arts & Sciences Electronic Theses and Dissertations
Objective: Phenylketonuria (PKU) is a hereditary metabolic disorder associated with cognitive compromise. Diffusion tensor imaging (DTI) has allowed detection of poorer microstructural white matter integrity in children with PKU, with decreased mean diffusivity (MD) in comparison with healthy children. However, very little research has been conducted to examine the trajectory of white matter development in this population. The present study investigated potential differences in the developmental trajectory of MD between children with early- and continuously-treated PKU and healthy children across a range of brain regions.
Methods: Children with PKU (n = 31, mean age = 12.2 years) were …
Inattention And Hyperactivity Among Preschool Age Children Born Prematurely, Andrew Heitzer
Inattention And Hyperactivity Among Preschool Age Children Born Prematurely, Andrew Heitzer
Wayne State University Theses
A large body of literature shows that compared to children born at term, preterm- children are at increased risk for difficulties with inattention and hyperactivity. Less consistency exists, however, in the limited body of research exploring the contribution of early biological risk to behavioral disinhibition within the population of children born prematurely. Therefore, our goal was to examine perinatal variables that may influence activity level and hyperactivity among preterm preschoolers. Ninety-eight preterm (23.4 - 33.9 weeks gestation) preschoolers (3-4 years) participated in the study. Direct measures of inattention and hyperactivity as well as parental ratings were used to evaluate behavior. …

Neuropsychological Outcome In Relation To Duration Of Early Orphanage Experience, Jacquelyn Marie Perry Avery
Neuropsychological Outcome In Relation To Duration Of Early Orphanage Experience, Jacquelyn Marie Perry Avery
Wayne State University Dissertations
In this sample of 144 children with a history of prior orphanage experience, increasing duration of institutionalization is related to decreasing performance for a number of cognitive domains, most consistently verbal measures and executive Functioning measures. The relationships with duration for measures requiring visual-spatial skills were more mixed and a visual reasoning task was found to significantly relate to duration but not a measure of visual memory or a measure of nonverbal achievement. There was little evidence to support a relationship between the duration of institutionalization and fine-motor dexterity. The strongest relationships with duration were observed for language measures followed …
